A lead bullet moving 500 m/s hits a wooden block and stops. Find its change in temperature if 1/10 of the energy is changed to heat in the bullet.

i need 3 examples of thermometric liquids

water at a gauge pressure of 3.8 atm at street flows into an office building at a speed of 0.60 m/s through a pipe 50 mm in diameter. The pipe tapers down to 2.6 cm in diameter by the top flooe, 18m above the street, where a faucet has been left open. calculate the flow velocity and the gauge pressure in such a pipe at the top floor.
